Alberta wildlife officials identify case of mad moose disease
Southern Alberta wildlife officials have identified what they say is the first case in Canada of a moose suffering from a neurological disorder associated with mad cow disease.
The diagnosis of chronic-wasting disease, also called CWD, was made after tests on an animal killed in a collision with a vehicle last November near Medicine Hat.
Moose lungworm shows links to wild canids
A three-year study has determined that lungworms found in Maine moose likely begin their life cycle in wild canids, including coyotes and foxes, before being transferred to moose, according to a Maine Department of Inland Fisheries and Wildlife press release.
The DIF&W has been collaborating with the University of Maine Animal Health Lab, in examining the presence of lungworms, or Dictyocaulus spp., in moose. Lungworms have been noted in moose that have been found dead in late winter with heavy winter tick loads and the combination of both parasites has been implicated as a cause of calf mortality, according to the release.
State biologists will collect elk to research cause of hoof disease
State wildlife biologists plan to kill and collect samples from elk calves in several locations to help determine the cause of hoof disease in elk in southwest Washington.
Starting this month, up to five young elk will be taken from industrial forestland in Pacific County for a comparative study of elk from the Cowlitz River Basin, where the disease has spread rapidly among elk since 2008.
The hoof disease results in broken, deformed hooves and lameness that can hinder an elk’s ability to survive. The Washington Department of Fish and Wildlife (WDFW) has been working with specialists here and abroad to gain a better understanding of what is causing the disease in southwestern Washington elk.
“The scientific literature suggests as many as 40 possible causes of hoof disease in domestic animals, ranging from bacterial infection to nutritional deficiencies,” said Dr. Kristin Mansfield, WDFW veterinarian. “We have to understand the cause of this problem in elk before we can have any hope of managing it in our state.”
Mansfield said the condition found in Southwest Washington appears to be distinct from hoof diseases found in livestock and other wild animals. To help narrow the search for the cause, calves will be used in the study because they are less likely to have other health problems that may affect the findings, she said.
